Medical Billers and Coders transform verbal descriptions of disease, injuries, examination results, diagnostic tests, treatment methods, and all other healthcare provider services and procedures into standardized numeric or alphanumeric designations which then could be turned into a bill for the payment or insurance reimbursement. You would also be prepared for processing claims for commercial insurance companies, government medical claims such as Medicare, medical and workers compensation, Tricare and disability insurance claims as well as Blue Cross and Blue Shield.
